Coupling Network Resonator

AI Thread Summary

The discussion focuses on a resonator composed of 64 gap-coupled small resonators, exhibiting four distinct resonances at 5.7GHz, 6.25GHz, 6.78GHz, and 7.172GHz, with the coupling strength decreasing at higher frequencies. The main inquiry is about methods to enhance the coupling specifically at the 6.78GHz resonance. Participants explore potential techniques and adjustments that could improve coupling efficiency. The conversation emphasizes the importance of understanding the underlying physics of resonator coupling. Overall, the thread seeks practical solutions for optimizing resonator performance at targeted frequencies.

Hello,I have built a resonator which consists from 64 gap coupled small resonators. I have 4 resonances 5.7Ghz (the strongest coupling) 6.25Ghz 6.78Ghz 7.172Ghz as shown below . the coupling of the resonances getting smaller as the frequency rises. Is there a way to increase the coupling on the 6.78Ghz resonance?
Thanks.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
